|Daughter taxa (time control age-window is: 0-800Ma)
Nannoliths, miniscule (<1 µm), formed of 3 nearly co-planar rays, often with a distal process. Cells monomorphic, often saddle-shaped, with long flagella and haptonema.
Coccoliths formed of single angular calcite unit, coccospheres flower-like
Coccosphere formed of a few cap-shaped nannoliths
Small to medium pentagonal liths, with narrow rim and granular central area plate. Dark image in LM.
Nannoliths kite-shaped plates with raised margin on both sides
Parent taxon (Nannolith families inc sed): Haptophytes forming calcareous structures not obviously homologous with heterococcoliths, holococcoliths, or discoasteralids
This taxon: Three apparently unique genera, not-included in described families
